A company plans to develop a prototype weeding machine that [#permalink]

Question Stats:
0% (00:00) correct

A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.
Which of the following is a consideration in favor of the company’s implementing its plan to develop the prototype?
A. There is a considerable degree of variation in shade of color between weeds of different species.
B. The shade of color of some plants tends to change appreciably over the course of their growing season.
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.
D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.
E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.

Look like A ....
D is looking well beyond the scope

also go with A..... this is the assumption on which the argument is based. on this basis the company is developing the prototype of the machine...

As much as D looks tempting, A can be directly inferred from the question stem.

D)...IMO A) is weakening the usage of the prototype, because it wont be able to distinguish between weeds and plants.

christoph, I totally agree.
We need to be able to distinguish between weeds and plans.
D for me too.

I would go for E.
E as it makes economic sense to free farm workers from doing de-weeding work,if they can tend to other agricultural duties.
D - I didn't pick D because , genetic engineering is required to see the efficacy of the prototype, which IMO not a strong reason to develop a prototype , and more-over what is the need to change the color of crops , which at present might be distinct from any of the weeds.

I believe D should be the answer, and here is why
The argument states that the machine will be able to distinguish plants from weeds solely on the differences in the shade of color. D states that plants can be bred to have a distinct shade of color. This means that a plant can be bred with a distinct shade of color that is completely different from that of the weeds. Thus, this development will favor the development of this machine.

I would go for C as it is the only choice which would favour the company's decision to develop the prototype.
A fails because it does not favor co. as it makes the comparison between crops and weeds difficult
B fails as the machine still wont be able to distinguish between crops and weeds
D fails because it is out of the scope.
E. unnecessary information..!

i go with D
A. is weakining company proposed implementation. Diferencies in color of diferent species will not allow this equipment to work correctly.
b. is the same as above
c. is weakining because it is showing us that there is other common technic to distinguish weeds from crop.
d is out of scope
e. is giving some justification to implement this equipment
what is OA?

I would go with E, because of the obvious ecnomomic benefit.
Don't agree with A becuase the sentence says variation of color in weeds of different species, not between weeds and crops.

Which of the following is a consideration in favor of the company’s implementing its plan to develop the prototype?
A. There is a considerable degree of variation in shade of color between weeds of different species.
Tells us nothing about the color of the plants (as we are told, the new technology uses differing colors between crops and weeds). The trap - Eliminate
B. The shade of color of some plants tends to change appreciably over the course of their growing season.
Makes the technology non-efficient. Eliminate
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.
So what? WE are concerned with the new technology, which uses color to distinguish weeds from crops. WE dont care about manual distinction - Eliminate.
D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.
Straight Answer. Crops can be bred to have distinct colors, which can enable the technology separate crops from weeds.
E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.
We are not concerned about manual processes - Eliminate (irrelevant)
It's a straight (D).
